Application flied w s 22, 1920. SriallNoJ418fi22i To all whom itmct e concern:

Be it known that 1, Max It. Konunnii, a citizen of the United"States, esidingatElmwood, in the county of Hartfordand State of Qonnecticut, have invented certain new and useful Improvements in Floor or Ceiling Plates, of which the following is a specification.

This invention relates to a floor or ceiling plate. I have a number of niotivesin view among the principal ones of them be ing the provision of an article of this character which is capable of exceedingly inexpensive construction, which possesses the maximum strength and whichalso consists of a very few parts. As a matter of fact the plate itself outside of the holding springs which are usual in this kind of article, and the )ivot,preferably comprises but two parts bviously therefore the device can be easily, inexpensively and quickly made. 1 p

In the drawings accompanying andformingpart of the present specification I have shown in detail a form of. embodiment of the invention which to enable those skilled in the art to practise the same will be set forth fully in the following" description.

The novelty of the invention willbe included in the claims succeedingsaid de scription. I am not restricted to this exact showing. I maydeparttherefrom in several particulars within the scope of the invention defined by the claims.

Referring to said drawings: Figure 1 is a bottom plan view of a floor or ceiling plate involving the invention.

Fig. 2 is a detail in section of the rear or hinge portion of the plate.

Fig. 3 is a detail in section of a portion of one of thesections or halves of the plate.

Fig. 4; is a similar view of the latch portion;

Fig. 5 is a fragment of the insideof one of the sections. I l

Like characters refer to like parts throughout the several views.

'These floor or ceiling platesare generally applied to steam. or water pipes, for finishing purposes. They fit around the pipes adjacent the ceiling or the floor and ens to narily bear against theilatter. I As shown the plate comprises two semi-annular sec tions 2 and 3 usually of sheet metal. Each of the sections is of a half circle, their radial straight ends being in abutment as shown lar extension 7 integral therewith and overlying the extension 6, the extensions 6 and 7 being jointed to each other as by the pivot 8, which may as is common, consist of a rivet held in place by heading.

The flange 5 has at its front end shown in Fig. 1, when the plate is closed, for inthe forward integral projection 9 constitut" ing a convenient catch, to be engaged as I will later set forth,jby a latch associated as shown with the section 2 The flange 4: as illustrated is furnished at its front end with an. extension 10 which is laterally-forwardly bowed somewhat between its ends, and which has a notch or "slot 11 in its under usurfaceto receivethe catch 9. This latching portion 10 it will be seen extends laterally beyond the front end of the section 9.

The two sections 2 and 3 are assumed tobe To open the ring the following procedure maybe adopted. The sections 2 and 3 will latched together in Fig. 1.

catch 9 out of the notch 10 at which time the sections can be easily Tspread apart, swinging on the pivot 8. The under side of the latching portion 10 is beveled or rounded off as at 12, the beveled surface enthereof extending into the opening present edjointly by the sections Qand 3, the result being that when the ring is closed upon a pipe or something of a similar nature it will berelatively tipped sufliciently to carry the be yieldingly engaged by the free portions of the two springs. The slots 13 to which I have referred may in part be formed in the lugs, 15 extending in pairs from the respective flanges 4 and 5.

What I claim is:

1. A floor or ceiling plate comprising two semi-circular sections of sheet metal pro:

- of the sections having meansto releasably connect the sections together.

2; A floor or ceiling plate comprising two semi-circular sections of sheet metal provided along their inner edges with semicircular integral flanges, the rear end portions of the flanges having integral rearwardly-extending extensions pivotally connected together, and the front end portions of the flanges having integral portions to releasably connect the two sections together at the front end of the plate.

In testimony whereof I afiix my signature.
